At the Optical Computing Lab in the Jet Propulsion Laboratory (JPL) a binary holographic data storage system was designed and tested with methods of recording and retrieving the binary information. Levels of error correction were introduced to the system including pixel averaging, thresholding, and parity checks. Errors were artificially introduced into the(More)
Introduction: NASA’s future missions would require massive high-speed onboard data storage capability to Space Science missions. For Space Science, such as the Europa Lander mission, the onboard data storage requirements would be focused on maximizing the spacecraft’s ability to survive fault conditions (i.e. no loss in stored science data when spacecraft(More)
An innovative holographic memory system has been developed at JPL for high-density and high-speed data storage in a space environment. This system utilizes a newly developed electro-optic (E-O) beam steering technology to achieve a design goal of up to 250 Gb storage in a cubic photorefractive crystal with up to 1 Gb/sec transfer rate. Recently, a compact(More)
Recent technical progress in developing a compact digital holographic memory system is presented. Due to rapid advancement in data input and output devices, electro-optic beam steering technology, and diode laser source, a compact holographic memory brassboard for digital data storage has been integrated. The system consist of a 1 Meg pixel binary spatial(More)
